Applied online for Bloomberg's FSD position. Received an email about two weeks later that I passed screening and to write an online programming test in your choice of programming language. I wrote the C test, which is fairly easy, but it requires you to be familiar to be with the Standard C library functions, some I/O functions, and simple string manipulation. There is 30 questions in total with 3 minutes per question.
I estimate I performed okay, but probably did not know well enough because did not know a few answers from the top of my head. Waiting to hear a response back. Either way, it is a good refresher test for interviews.
